I have a question.  I have guest posting enabled and there is one dude who is maliciously spamming my board using what I believe to be imacros.  Would this stop someone who floods the board with the same topic over and over again?  Thank you.

More clarification:
I use guest posting on my forum.  Besides this mod I use the standard smf "Anti-Spam Verification" (there are posts about this somewhere in this community that tell you how to set it up) for every non-member post in the guest area.  I do not have a spam problem in my guest area.
O:)

Block china in your htaccess file!

Dp something like this list for your htaccess file.

Not  necessary for RC3, Bad Behavior stops the riffraff soooo very well.  ;D
Now 1.1.11, htaccess works to some degree, but still have spammers trying to use the quick reply with random IPs. ie: never use the same IP more than twice.

Thanks for the feedback.  I am interested to know how it works on other sites besides my own.

Interesting.  Thank you for the info.  :)

I will look into the sort for the next version.  O:)

Permitted users are questionable and may not be real spammers.  The reason they are listed is because they should be watched.  If you find one please email me the details.   ???

Bad Behavior (BB) should be used in along with httpBL mod.   The current release version of BB includes honeypot but it does not have all the nice forum features as httpBL so I left that portion out.  A feature that I added that is not in the origional is that when you enable httpBL the Bad Behavior warning page includes a present in the form of the Honeypot trap link from httpBL.  The other unique feature is the optional SMF caching.   :o

Here is what happened on my site:
Stop Spammer 2.3.7 (current state--On) Has caught nothing since BB was turned on.
httpBL 2.3.4 (current state--ON, shows Honeypot trap link)
Bad Behavior 1.0.0 (current state--On, strict mode enabled)
avatar_verification_1.0 (current state--On, over 100 verification images)  Gets 5-10 hits a day but nothing has passed it.  The hits seem to be spammers who are getting caught by other means.

The trend I have seen is that with Bad Behavior in strict mode is that it blocks their proxies and other bad things.  I saw around 180-190 in my first week.  Then the humans tried turning off the proxy to get past BB but then the httpBL Mod caught them.

They were not happy with my site so they decided to assault me with a DOS -- over 300 hits/ day several times.  Every attempt failed with BB and httpBL enabled.  fyi - I made a lean httpBL warning screen that is like the BB warning screen just for my site to reduce bandwidth usage during these attacks.

After a several months they seem to have mostly given up.  Now I see only a few hits a day from both mods - Spam free!

Mine says <!-- Bad Behavior 2.1.2 run time: 0.000 ms -->. Does that mean it's not running at all? Also, will this allow google bots to browse the forum?

Awesome, so should I install httpBL 2.3.4 too (will it conflict with this mod?) and how do I enable strict mode? Also I don't understand the cache thing. Mine is set to 0. Could you explain?

Thanks!

You can install httpBL with no conflicts.

and how do I enable strict mode?

Check "strict" under the security option in the admin panel.  See attached.

Also I don't understand the cache thing. Mine is set to 0. Could you explain?

If you click on the i next to cache duration the help will say: 
Quote
The buffer time in seconds that the SMF Caching System is allowed to keep information for a readable IP address between Bad Behavior look-ups.  Because bots can look at multiple pages in your forum in a short amount of time this setting will allow either them or a visitor to view the forum or see the banned message within the duration using the least amount of processing effort.

If the SMF Caching System is not enabled you will get a warning message in the error log.

The time delay can be set between 0 and 99 seconds.  Zero disables this feature and prevents error log messages.  This number should be adjusted as low as possible based on server load.  Default is 0 seconds.

That is because you are the admin and you are bypassed.  It does not check admins.  If your IP is not whitelisted, log out to see the speed.

More on caching duration since I am complicated.   Say you look at your cpanel and find the following bad bot hit your site:

15:06:55
15:06:58
15:07:02
15:07:04
15:07:07

The total duration of this bots rampage is 30 seconds (58-37+7+2).  So if you set cache duration to 8 Bad Behavior will check the bot 3 times during it's visit.  The remaining hits will be a repeat of the last check.

If the bot failed at "15:06:37" every hit on your site will be immediately rejected for 8 seconds.  After that it will check again at "15:06:45".

To date I have not seen a bot fail the first hit and ever pass a second hit.  But someday that may happen.

Standard Bad Behavior does not include this feature.  It is fast enough to check every hit.  This feature should only be used when you have a really bad bot problem or your site is large.

Yes it did.  If you do not have IE click within the highlighted area for more details.  If you have ie click on the underlined denied text to see the details.

No, that means it ran so quickly it didn't even taken 1/1000 of a second (I think ms is wrong here, unless you're really measuring 1/1,000,000th of a second)

I really did not look at that part too much since it was part of the std BB package.  EDIT  :)

EDIT:
Now I am soooo confused.   :-[

ms was correct.  It multiplies 1000 to the number before displaying it.


having a bad bad day...  ;)

and yes, that time measurement code does display in slower blogs/ forums.

$bb2_mtime = explode(" ", microtime());
$bb2_timer_start = $bb2_mtime[1] + $bb2_mtime[0];

end:

$bb2_mtime = explode(" ", microtime());
$bb2_timer_stop = $bb2_mtime[1] + $bb2_mtime[0];
$bb2_timer_total = $bb2_timer_stop - $bb2_timer_start;

Installed and working withour errors on RC3.

Followed the instructions, edited what needed to be edited and did the two part install.

Other than needing to chmod a few items ( my fault ), the install went without any problems.

Thanks
